On Sunday I took a walk to the UEL library, then I thought: "Oh why not?" and walked to the Thames Barrier Park for a sit in the cafe and a coffee. Then walking around the park I looked at the other side of the barrier and thought: "Oh why not?" and walked to the otherside! Google maps seems to think I flew over, but it wasn't that easy! 10 miles not easy. In the deffence of Google maps I have realised keeping the GPS on will give a good route record. From now on I know what to do.
